CATTLE-GUARD.

QdGATS.

Application filed November 21, 1908.

To all whom it may concern:

Be it known that I, ARTHUR M. WHITE, a citizen of the United States,residing at Greenwood, in the county of Clark, State of lVisconsin, haveinvented certain new and useful Improvements in Cattle-Guards; and I dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to make and use the same.

The invention relates to cattle guards of the class designed to preventcattle from entering the right of way of a railroad from a public road.

One object of the invention is to provide an improved generalconstruction of cattle guards of this character in which the operatingparts will be protected from the influences of the weather and thusobviating freezing up in cold and snowy weather.

Another object of the invention is to improve the general constructionof a cattle guard of this character and render the same simple andefiective in operation.

A third object of the invention is to provide a cattle guard of thischaracter which will permit and encourage the passage of any cattlewhich may stray upon the main line through a broken fence and endeavorto leave the same to pass out upon the public road.

.Vith the above and other objects in view, the invention consists, ingeneral, of a tilting platform, a tilting fence, and mechanism foractuating the same.

The invention further consists in certain novel details of constructionand combinations of parts hereinafter fully described, illustrated inthe accompanying drawings, and specifically pointed out in the claims.

In the accompanying drawings, like characters of reference indicate likeparts in the several views, and :-I*igure 1 is a top plan view of acattle guard constructed in ac cordance with my invention. Fig. 2 is asection on the line 22 of Fig. 1 showing the guard fence in depressedposition and the platform in raised position. Fig. 3 is a similar viewshowing the guard fence raised and the platform depressed as is the casewhen cattle endeavor to pass thereover. Fig. 4: is a bottom plan view ofthis inven tion.

The numeral 10 indicates the casing of Specification of Letters Patent.

Patented J an. 11, 1910.

Serial No. 463,872.

this invention and this casing is preferably divided into side portions11 and a central portion 12 by means of partitions 13. Each of the sideand central portions is provided at the end adjacent the public roadwith a pair of ears 14. At the opposite end of each of these partitionsthere is provided a pair of ears 15. The last mentioned pair of ears arespaced at some little distance from the adjacent end and serve tosupport a bar 16 whereon is mounted a gate frame 17 provided with aheavy central bar 18 for purposes hereinafter to be described. This gateframe is pivoted intermediate its ends and at its inner end is providedwith a cross bar 19 whereon is mounted a pair of rollers 20. Theopposite end of this gate frame is weighted as at 21 so that it normallylies in the position shown in Fig. 2. Between the extreme end of thecasing and the bar 16 is a platform 22 supported on the sides and on theend of the casing. The ears 14 serve to support a bar 28 which isconnected to a platform 24 by means of standards 25. This platform isprovided with a central brace member 26 Ushaped in cross section and theend of the platform opposite the bar 23 is provided with track sectionsas indicated at 27. The lower parts of the track ends form curvedextensions 28 and adjacent the extensions 28 and the tracks 27 aretriangular stops 29. It is to be observed that these extensions 28strike against the under sides of the platform extension 22 thus actingas stops to limit the upward movement of the swinging platform 24:. Thisplatform is so arranged that the bottoms of the tracks 27 rest on therollers 20. Suitably positioned between the side walls of the casing arestops 30 which limit the downward movement of the free end of theplatform 2%. It will thus be seen that there are three of theseplatforms and three gate sections and that these are positioned with thecentral platform between the rails and the outside platforms outside ofthe rails so that no matter in what direction the cattle attempt to passover the device they are obliged to step upon some one of the platforms24.

In the operation of the device let it be supposed that cattle areattempting to pass from the main road to the right of way. As soon asone of the cattle steps upon one of the platforms 24 the free end of theplatform will be depressed and the gate actu-' ated thereby will beraised. If the gate be raised to such position as to jam the sameupright the next locomotive Will depress the same by striking the centerbar 18. If cattle get on the right of way through a broken fence or thelike they can readily pass over the gate and cross the stationaryplatform If, then, they pass upon the movable platform the gate risesbehind them and hustles them quickly out on the public road.

It is to be observed that all of the oper ating parts are held protectedfrom the weather by the platforms 22 and 24 and that the device is thusprotected from freezing up in cold and snowy weather. It is further tobe noted that by reason of the construction of the platform 2st beingloosely mounted in the ears 14 the same may be readily removed forcleaning the pit formed by the casing.

Having thus described the invention, what I claim as new, is

1. In a cattle guard, a casing, rail support ing division membersextending longitudinally of said casing, pairs of U-shaped ears heldadjacent one end of said casing, one pair of said ears being disposed ineach of the divisions of the casing, a bar supported in each pair ofears, a platform fixed to each of said bars, a gate pivotally mountednear the other end of the casing in each of said divisions, each of thegates being provided with a frame having rollers upon its inner endadapted to extend beneath and support the free ends of the respectivehinged plati forms, stops on the platforms to limit the movement of therespective rollers, other stops fixed in said casing to limit thedownward movement of the free ends of the platforms, and a second seriesof platforms each held in one of said divisions between the free end ofits respective first platform and the end of the casing.

2. In a cattle guard, a casing, rail supporting division membersextending longitudinally of said casing, pairs of Ushaped ears heldadjacent one end of said casing, one pair of said ears being disposed ineach of the divisions of the casing, a bar supported in each pair ofears, a platform fixed to each of said bars, a gate pivotally mountednear the other end of the casing in each of said divisions, each of thegates being provided with a frame having rollers upon its inner endadapted to extend beneath and support the free ends of the res ectivehin 'ed )latforms, stops on the platforms to limit the movement of therespective rollers, other stops fixed in said casing to limit thedownward movement of the free ends of the platforms, and a second seriesof platforms each held in one of said divisions between the free end ofits respective first platform and the end of the casing, all of saidplatforms being arranged normally to form a substalr tially smoothunbroken surface.

In testimony whereof, I afiix my signature, in presence of twowitnesses.
